Yes it did, with brass insert.That one footpeg mounting hole seems to have had a previous repair as well.
The cam sprocket you need is a two-hole 28T. It is a CRF50/70 style. You will also want to get the CRF50 style cam sprocket bolts (the ones with 8mm hex heads) and the matching cam cover with the little stopper arm on it. If you use the original screws with the 9mm hex heads, they will contact the center of the cam cover and may break loose, causing the cam sprocket to fall off (ask me how I know.) If you use the original cam cover without the stopper arm, the cover can spin and fall off.Ok, I did a bit of research and found the correct cam sprocket. I wish it wasn`t such an ivestigation process to order partsfor these bikes, especially engine kits....
So the timing ratio is 2 to 1. The crank sprocket being 14T, I need a 28T. I took a secure leap of faith for the model and ordered it from T-Bolt. model TBW0861. There`s only 2 types with 28T from their website, 2 hole or 3 hole model. That was easy enough.
I got 2 different spark plugs too.
As for the timing chain length, I got an 84 link model from DrATV a while back.
